Last week we wrote about I-Can! E-File, a free electronic filing service for your federal income taxes. It’s a great idea, and we’re thankful to the Legal Aid Society of Orange County for doing something like this—but you might want to find an alternative this year and give them some time to work out the kinks. Today a reader emailed us to point out that icanefile.org’s password system can be easily cracked, because instead of letting you choose an original password, it requires you to use your name and social security number to set up an account.

I-CAN! is a web-based tax preparation tool that will file your tax return completely free of charge. I-CAN has no eligibility criteria or income restrictions and will eFile your state return for free if you live in California, Michigan, New York, Pennsylvania or Montana. It almost sounds too good to be true. So why isn’t I-CAN! a member of the IRS’ Free File Alliance?
